0fb8828fe2 - Call fork1() directly instead of calling rfork() so that it doesn't mask
out RFSTOPPED.
- Lock the child process when settings p_sigparent instead of locking the
  parent.

6ad0e7c5cc Create clone'd linux processes as stopped processes at first and don't
actually make them runnable until after the emulator layer has had a chance
to perform fixups.

9ccd73f2ee Add MODULE_DEPEND() for the sysvipc modules. This allows the linulator

c9eeb59a01 Sort out the umount breakage introduced in the last 2 revisions.
Please note:
When committing changes to this file, it is important to note that
linux is not freebsd -- their system call numbers (and sometimes names)
are different on different platforms.  When in doubt (and you always need
to be) check the arch-specific unistd.h and entry.S files in the linux
kernel sources to see what the syscall numbers really are.

Also clean up debugging output in a slightly more uniform fashion.

The default behavior remains the same (all debugging output is turned on)

466b14d758 Don't unregister the ioctl handlers before we verified we
can unload. Doing so leaves the linuxulator in a crippled
state (no ioctl support) when Linux binaries are run at
unload time.

While here, consistently spell ELF in capitals and perform
some minor style improvements.

930a65fe47 Use the linux_connect() on alpha rather than passing directly through
to our native connect().  This is required to deal with the differences
in the way linux handles connects on non-blocking sockets.

This gets the private beta of the Compaq Linux/alpha JDK working
on FreeBSD/alpha

922683e01a Enable linux thread support on the alpha. The guts of linux_clone was
mainly cut-n-pasted from the i386 port, except for the method of setting
the child's stack which is the only MD part of this function.

I've tested with the example apps shipped with the linux threads source
code (ex1-ex6) and with several binary builds of Mozilla.

806d7daafe Make MINSIGSTKSZ machine dependent, and have the sigaltstack
syscall compare against a variable sv_minsigstksz in struct
sysentvec as to properly take the size of the machine- and
ABI dependent struct sigframe into account.

The SVR4 and iBCS2 modules continue to have a minsigstksz of
8192 to preserve behavior. The real values (if different) are
not known at this time. Other ABI modules use the real
values.

The native MINSIGSTKSZ is now defined as follows:

Arch		MINSIGSTKSZ
----		-----------
alpha		    4096
i386		    2048
ia64		   12288

e70ce4d9c5 fix linux_termio and linux_termios structs on alpha. alpha differences
are in the termios struct (probably because linux wants to be compatible
with the osf/1 termios struct), not the termio struct.

7936339495 A start at an implemention of linux_rt_sendsig & linux_rt_sigreturn
and associated user-level signal trampoline glue.

Without this patch, an SA_SIGINFO style handler can be installed by a linux
app, but if the handler accesses its sip argument, it will get a garbage
pointer and likely segfault.

We currently supply a valid pointer, but its contents are mainly
garbage.  Filling this in properly is future work.

This is the second of 3 commits that will get IBM's JDK 1.3 working with
FreeBSD ...

dee4ec33cf When sigaltstack is called with a stack size that's not smaller
than LINUX_MINSIGSTKSZ but smaller than MINSIGSTKSZ, cheat and
pass MINSIGSTKSZ to the kernel. This is a workaround.
